The list must be syntactically correct, +it consists of one or more cipher strings separated by colons. Commas or +spaces are also acceptable separators but colons are normally used, \&!, \&- +and \&+ can be used as operators. + +For OpenSSL and GnuTLS valid examples of cipher lists include 'RC4-SHA', +\'SHA1+DES\', 'TLSv1' and 'DEFAULT'. The default list is normally set when you +compile OpenSSL. + +You'll find more details about cipher lists on this URL: + + https://curl.haxx.se/docs/ssl-ciphers.html + +For NSS, valid examples of cipher lists include 'rsa_rc4_128_md5', +\'rsa_aes_128_sha\', etc. With NSS you don't add/remove ciphers. If one uses +this option then all known ciphers are disabled and only those passed in are +enabled. + +For WolfSSL, valid examples of cipher lists include +\'ECDHE-RSA-RC4-SHA\', 'AES256-SHA:AES256-SHA256', etc. + +The application does not have to keep the string around after setting this +option. +.SH DEFAULT +NULL, use internal default +.SH PROTOCOLS +All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc. +.SH EXAMPLE +.nf +CURL *curl = curl_easy_init(); +if(curl) { + curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/"); + curl_easy_setopt(curl, CURLOPT_SSL_CIPHER_LIST, "TLSv1"); + ret = curl_easy_perform(curl); + curl_easy_cleanup(curl); +} +.fi +.SH AVAILABILITY +If built TLS enabled. +.SH RETURN VALUE +Returns CURLE_OK if TLS is supported, CURLE_UNKNOWN_OPTION if not, or +CURLE_OUT_OF_MEMORY if there was insufficient heap space. +.SH "SEE ALSO" +.BR CURLOPT_TLS13_CIPHERS "(3), " CURLOPT_SSLVERSION "(3), " +.BR CURLOPT_PROXY_SSL_CIPHER_LIST "(3), " CURLOPT_PROXY_TLS13_CIPHERS "(3), " +.BR CURLOPT_USE_SSL "(3), " |
